二维有源相控阵天线跟踪技术研究

Research on tracking technology of two dimensional active phased arrays antenna

当载体姿态变化时,利用惯导信息引导安装在移动载体上的二维有源相控阵天线波束指向卫星。首先对卫星在地理坐标系、载体坐标系和天线坐标系中的位置进行简要介绍,然后对跟踪目标角进行解算,最后通过跑车测试,验证了该跟踪技术的可实施性。

The two dimensional active phased arrays antenna is installed in a vehicle.It is led to the satellite by the information of INS,when the attitude of vehicle is changing.In this paper,it introduced the position of satellite in the local-level frame,in the body frame and in the antenna frame firstly,then calculated the target value on tracking satellite,lastly validated the realization of the tracking technology by testing.
